Researchers theorize that taking nitric oxide supplements could enhance the delivery of oxygen to muscles. This could potentially improve athletic performance and reduce soreness after a workout.According to an article in the journal
Sports Medicine, studies have shown that taking nitric oxide supplements may enhance tolerance to exercise. However, this only applies to those who did not exercise regularly or only exercised at a moderate rate.
The research has not shown that nitric oxide supplements can help elite athletes. Researchers carried out these studies on young males, so they do not know how nitric oxide supplements may affect older people and females.
Reducing erectile dysfunction
Because nitric oxide supplements enhance blood flow, researchers have conducted studies to determine if it could enhance blood flow for people with erectile dysfunction (ED).
According to an article in the journal
Future Science OA , some studies have shown taking nitric oxide may reduce ED in those with mild to moderate ED. Trusted Source Reducing high blood pressure in pregnancy
Preeclampsia, which is a form of high blood pressure that can occur in pregnancy, can be dangerous for both the woman and baby.
A 2005 study in the
European Journal of Clinical Investigation found that pregnant women who took L-arginine supplements for a prolonged period had lower blood pressure readings than pregnant women who did not take L-arginine. Trusted Source
Although researchers need to conduct more studies, the results are promising for women struggling with high blood pressure in pregnancy.
Other reported benefits
People take nitric oxide for a variety of reasons, many of which do not have any scientific research to support them.
Some of the reported benefits of nitric oxide supplements include:
enhancing weight loss
improving lung function in those with cystic fibrosis
treating altitude sickness
improving recovery after major trauma or injury
preventing the common cold
reducing the side effects of memory loss
healing diabetic foot ulcers
Most of these benefits are anecdotal, meaning that people may have reported a benefit, but there is no proof backed up by a scientific study.
